Decision table and DSL
by philippe rouxel
Hi,
I post this, but got no echo:
My project is multi-national: the business model is in English, but
some rules depend on the user's country (fr, de).
This rules have to be edited in the locale language.
For editing a rule, the guided rule editor and a DSL are fine.
But for a decision table, I did not find a way to use a DSL.
So, what is the best strategy:
+ use a template for each DT and loose the benefits of sharing the translation.
+ use an expander for each DT that parse a DSL and translate the terms.
Or may be an other solution?
Regards,
Philippe

Registration:
http://community.jboss.org/wiki/DroolsBootCampSanDiegoApril2010
The boot camp is free, you only need to turn up, but please register
here, http://community.jboss.org/wiki/DroolsBootCampSanDiegoApril2010.
This page also is a live and more informed version of the information
contained here - please read it thoroughly.
Who Should Attend: See the registration page above for more detailed
information.
Overview
Mon-Tue (medical only)
The the first two days are exclusive to the medical and healthcare
communities and only people from medical and healthcare organisations or
with a medical background will be allowed to attend.
Wed (medical slant - open to all)
Keynote - James Taylor (Smart Enough Systems) "Smarter systems for
uncertain times".
The third day will still maintain a medical slant, wrapping up the last
two days, but we will open it up for those that want to observe or
participate. We will try and cover topics that will be interesting to
all there, even if not from medical background, just be aware that
medical discussions take priority. It is recommended that most people
start on the Wednesday, especially as we have an excellent keynote
speaker for everyone.
Thu-Fri (general topics - open to all)
The last two days is open to all and will hvae no specific topic. It is
likely we'll repeat a few talks from mon-tue that are relevant to new
comers.
Agenda
Other than the Wednesday keynote with James Taylor, we do not yet have
dates and times allocated for talks, as we are still waiting for all
talks to be proposed. So if you are thinking of talking, hurry up and
let us know :) (see registration page for more info). The registration
page will be kept up to date with talks, and contains information and
ideas on talks we'd like people to give; basically anything you think
people attending will be interested in - it does not have to be drools
specific. The current proposed talks are:
*Name* *Talk*

memory issue (memory leak?) on trunk (probably due true modify changes)
by Geoffrey De Smet
Hi guys,
With great improvements usually come instability for a while :)
Trunk has memory issue, probably a memory leak of a small object.
I've run ExmaminationBenchmarkApp with the program arg "short" 3 times
with the exact same configuration (it is a 100% reproducible run):
1) Before the true modify changes with 512m max memory
Succeeds (100 steps but even 10000 steps work) with no slow down.
2) After true modify changes with 512m max memory
Fails after 27 steps, starts slowing down at 24 steps.
3) After true modify changes with 1024m max memory
Fails after 57 steps, starts slowing down at 54 steps.
Both 2) and 3) fail with the exception:
Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit
exceeded
So it's not a heap space error or a perm space error, but a GC overhead
limit instead. Literally this means it's doing more GC then running,
but 99% of the time this means that the heap is so full that the GC has
little or no free space to work with.
This kind of memory leak happens when the iteration make 101 objects but
only removes 100 objects and the iteration is run a lot (like 10000+ times).
You don't get a heap space error, because before that happens,
there is point where you have a garbaged collected free memory for 10
objects and a ungarbaged collected free memory for 100 objects. At that
point the GC is running over 98% of the time, which is a VM treshold and
the error is thrown,
even though 10 iterations later you would get a heap space error.

3 issues with true modify, but PatientAdmissionScheduleApp does work
by Geoffrey De Smet
Found another issue with the true modify changes: 3 of my examples don't
work (NQueens, Travelingtournament, Examination), due to distinct causes.
PatientAdmissionScheduling does work and it's about 4% faster on first
sight.
It's a linear improvement, not an exponential improvement.
Nothing world shocking (yet), but every little bit helps :)
Edson and Mark believe that true modify allows for new optimization,
which I believe might be an exponential improvement.
Once examination works I'll test if I can remove the TMS workaround I
needed before.
This will be a huge performance boost, but only for that specific example.
Here's the bug list:
1) Infinite loop in
org.drools.core.util.LeftTupleList.get(LeftTupleList.java:102)
2) NPE in
org.drools.core.util.RightTupleList.matches(RightTupleList.java:190)
because this.first is null in
return this.hashCode == tupleHashCode && this.index.equal(
this.first.getFactHandle().getObject(),
tuple );
3) NPE in
org.drools.reteoo.SingleLeftTupleSinkAdapter#propagateModifyChildLeftTuple,
line 198:
the leftTuple or the sink is null
childLeftTuple.getLeftTupleSink().modifyLeftTuple( childLeftTuple,
context,
workingMemory );

Accessing JCR repository directly
by Bernd Rücker
Hey guys.
I thought I better ask that question on the dev list, correct me if that
was a bad choice ;-)
I want to programmatically access the JCR repository from another
application (basically to author rules). I understood the RulesRepository
(which is a nice interface by the way). I tried to understand how the JCR
Session is created and can be accessed. As far as I found it, it seems
that a Seam Bean just starts everything (RulesRepositoryManager). Now the
question is: How can I access this from another application? Because the
workspace is locked, I cannot create another Session from there.
Wouldnt it be nice to bind the stuff in JNDI correctly or something like
that? Or if I do that, can I inject it into the Seam application? Or maybe
I can access the seam bean somehow from external?
I think it would be the easiest and best to access the JCR repos instead
of using WebDav or whatever if I am in another EJB3 application
Thanks a lot for any hint
Cheers
Bernd

Drools Clips build failure

Drools clips has a build failure on my machine, but strangely it doesn't

Re: [rules-dev] Accessing JCR repository directly
by Michael Neale
yes that was exactly my point. at that time we weren't prepared or willing
to create app specific wars/sars. In a perfect world the war would work in
all containers (that isn't really possible it seems) but also be able to
work in non EE containers (that may be a JNDI issue? eg with jetty can be a
hassle).
